Training Session 1

This 60-min video is a basic training on using HOMER2 from the online training session from March 4, 2013.

Training Session 2

This is the recording of the training session from April 16, 2014. This session covered several questions including:

• Excluding channels based on signal level, SNR, and source-detector separation
• Exporting HRF results
• Looking at channel cross-correlations
• Correction motion artifacts on OD rather than intensity
• A review of the GLM capabilities of Homer
• Some discussions about AtlasViewer

Displaying Different Channels Of Data in Homer2

This 4-min tutorial demonstrates how to select different channels of data to display. It shows how to select channels from individual sources or detectors, how to display data from multiple sources and detectors, and how to individually hide or deactivate specific channels of data.

Simple Probe

This is the basic introdunction to the screen layout of HOMER2, how to view data from different sources and detectors, how to execute a simple processing script to convert from intensity to optical density to concentration, how to bandpass filter the data, and how to block average the response to a stimulus.

Waterfall Plot and Fixed Plot Range

This is a short tutorial showing the waterfall plot feature, selecting multiple channels of data to display, and fixing the plot range.

Exporting a Data Trace

This tutorial shows how to export data traces from the plot window by right clicking on the line within the plot window. You have the option of saving the single trace, or all traces visible in the plot window. They are saved to a text file where the first column is the time vector and each subsequent channel is the data for one of the channels. The top of each column is labeled to identify the data type and source and detector.
